The $k$-Cap Process on Geometric Random Graphs

Probability 2022-11-16 v2 Discrete Mathematics

Abstract

The kk-cap (or kk-winners-take-all) process on a graph works as follows: in each iteration, exactly kk vertices of the graph are in the cap (i.e., winners); the next round winners are the vertices that have the highest total degree to the current winners, with ties broken randomly. This natural process is a simple model of firing activity in the brain. We study its convergence on geometric random graphs, revealing rather surprising behavior.

Comments

We edited to extend the analysis of the discrete k-cap process from 1-D interval graphs to constant d-dimensional graphs
